Functional TLR5 Genetic Variants Affect Human Colorectal Cancer Survival
Toll-like receptors (TLR) are overexpressed on many types of cancer cells, including colorectal cancer cells, but little is known about the functional relevance of these immune regulatory molecules in malignant settings. Here, we report frequent single-nucleotide polymorphisms (SNP) in the flagellin receptor TLR5 and the TLR downstream effector molecules MyD88 and TIRAP that are associated with al
Cerebral inflammation is an underlying mechanism of early death in Alzheimer's disease: a 13-year cause-specific multivariate mortality study.
Introduction: Although Alzheimer’s disease (AD) is associated with early death, its life expectancy differs greatly between patients. A better understanding of this heterogeneity may reveal important disease mechanisms underlying the malignancy of AD. The aim of this study was to examine the relation between AD pathologies and early death in AD caused by dementia. Methods: At a memory clinic, 247
Optimizing cost-efficiency in mean exposure assessment - cost functions reconsidered
Background: Reliable exposure data is a vital concern in medical epidemiology and intervention studies. The present study addresses the needs of the medical researcher to spend monetary resources devoted to exposure assessment with an optimal cost-efficiency, i.e. obtain the best possible statistical performance at a specified budget. A few previous studies have suggested mathematical optimization

Modeling astatine production in liquid lead-bismuth spallation targets
Astatine isotopes can be produced in liquid lead-bismuth eutectic targets through proton-induced double charge exchange reactions on bismuth or in secondary helium-induced interactions. Models implemented into the most common high-energy transport codes generally have difficulties to correctly estimate their production yields as was shown recently by the ISOLDE Collaboration, which measured releas
Chairmen's Summary
Several important observations emerge from this 2008 International Consultation "Bladder Cancer from Pathogenesis to Prevention". The following is a brief summary the issues that have been discussed in the articles from the meeting.
Clinical Examinations of the Rectoanal Inhibitory Reflex Correlated with Anography Findings, Histopathological Findings, and Clinical Outcomes
The diagnostic method for Hirschsprung’s disease (HD) involves rectal biopsy to determine the presence of histopathological findings for aganglionosis. Contrast enema (CE) and anorectal manometry help to support the indication for biopsies. Patients with HD lack a rectoanal inhibitory reflex (RAIR) that can be studied using manometry, ultrasound, or a modified contrast enema (CE), which provoke
Green IT in Practice: Virtual Meetings in Swedish Public Agencies
This paper presents and discusses how virtual meetings (VMs) can be used as a Green IT-measure in an organization, by analyzing the experiences and results from the project ‘REMM’ involving 20 public agencies in Sweden. The paper describes the methodology used in the REMM project, how progress and results have been monitored, evaluating how well the approach has worked out and discussing how appli
Low CSF Levels of Both α-Synuclein and the α-Synuclein Cleaving Enzyme Neurosin in Patients with Synucleinopathy.
Neurosin is a protease that in vitro degrades α-synuclein, the main constituent of Lewy bodies found in brains of patients with synucleinopathy including Parkinson's disease (PD) and dementia with Lewy bodies (DLB). Several studies have reported reduced cerebrospinal fluid (CSF) levels of α-synuclein in synucleinopathy patients and recent data also proposes a significant role of α-synuclein in the
Towards physico-chemical understanding of fibril formation of the Alzheimer disease-associated amyloid beta-peptide
Inconsistent condom use among Ugandan university students from a gender perspective: a cross-sectional study.
Background : Feminization of the HIV/AIDS epidemic has been a prominent phenomenon in sub-Saharan Africa. Inconsistent condom use among young people is one of the major risk factors in the continued propagation of the epidemic. Therefore, it is of importance to increase knowledge of gender aspects of condom use among young people. Objective : To investigate whether gender differences regarding ind
Memristive and Memcapacitive Characteristics of a Au/Ti-HfO2-InP/InGaAs Diode
This letter reports on room-temperature electrical measurements of a Au/Ti-HfO2-InP/InGaAs diode fabricated by atomic layer deposition and electron beam lithography. At forward bias voltages, the diode shows memristor characteristics, whereas at reverse bias voltages, the diode can be characterized as a memcapacitor. A parasitic accumulation layer of charges formed at the high-kappa oxide/InP inte
Observing Plasmonic-Molecular Resonance Coupling on Single Gold Nanorods
Strong plasmonic-molecular resonance coupling occurs between noble metal nanocrystals and organic adsorbates when the plasmonic resonance is degenerate with the molecular one. This interaction forms the basis for many fundamental studies and practical applications. We describe here the first direct measurement of the resonance coupling on single gold nanorods. The dark-field scattering technique i
eta Carinae: linelist for the emission spectrum of the Weigelt blobs in the 1700 to 10 400 angstrom wavelength region
Aims. We present line identifications in the 1700 to 10 400 angstrom region for the Weigelt blobs B and D, located 0.'' 1 to 0 ''.3 NNW of Eta Carinae. The aim of this work is to characterize the behavior of these luminous, dense gas blobs in response to the broad highstate and the short low-state of. Carinae during its 5.54-year spectroscopic period. Methods. The spectra were recorded in a low st
Resistance to change: Four interpretations
Although the phenomenon of resistance to change has gained considerable attention in organization theory over the years, the meaning of the concept is rarely discussed. In this paper, a conceptual framework is suggested that distinguishes between four interpretations of resistance and builds upon the two variables of changeability and emotionality. Each interpretation is based on various assumptio

TLR4 dependent heparan sulphate-induced pancreatic inflammatory response is IRF3-mediated
Background: Degraded extracellular matrix can stimulate the innate immune system via the Toll-Like Receptor-4 (TLR4). In the pancreas, syndecan-anchored heparan sulphate (HS) on the ductal epithelium can be cleaved off its protein cores by the proteases (trypsin and elastase) and potentially activate TLR4 signalling. Methods: To investigate this signalling event, a low sulphated HS (500 mu g/ml) w
